Korky Ultra Standard 2-Inch Universal Toilet Flapper 100BP

Universal fit for major brands

The Korky Ultra Standard 2-Inch Universal Toilet Flapper replaces worn flappers on toilets from American Standard, Briggs, Crane, Eljer, Kohler, Mansfield and TOTO. It is designed for homeowners and plumbers who need a reliable, drop-in repair part that works across the most common toilet models without special tools or brand-specific hunting.

Long-life Chlorazone rubber

The flapper is moulded from premium red Chlorazone rubber formulated to resist chlorine, hard water and common tank cleaners far longer than standard black rubber. That material choice gives it a service life that comfortably handles years of daily flushing cycles, while the universal 2-inch design means it seals properly on the wide range of flush-valve seats found in the brands listed.

Invented in 1950, made in Wisconsin

Korky invented the original toilet flapper in 1950 and continues to design and manufacture this Ultra series in Wisconsin, USA. That heritage means the geometry and rubber compound are refined from decades of field data rather than copied from a spec sheet, so the part you install today matches the profile that plumbing professionals have specified for generations.
